There will be plenty of opportunities to ring in the New Year at Vermont’s ski resorts Saturday night. We told you about the James Taylor concert at Stowe yesterday (8 p.m., Spruce Peak Performing Arts Center), but there’s much more. Family-centered celebrations are planned at Killington and Mount Snow in their hotel ballrooms with dancing, midnight champagne and cider for the kids. Okemo will host an early evening party from 6:30-9 p.m. with skating, snowshoe tours, horse and wagon rides, and a DJ-fueled party at the Roadhouse.
